The freshwater migration behaviour of winter-run steelhead (Salmo gairdneri) was studied on the Salmon River (Vancouver Island) between January and June 1986. Radio telemetry was employed to monitor in-stream movements and to determiine time and location of spawning. Between January 30 and May 7, 1986, 217 steelhead were captured by angling and beach seining in the Salmon RIver. Sixty-one fish were held for broodstock, 28 were radio tagged, 34 were anchor tagged, and the remainder were released untagged. The mortality rate from angling was 5.7% (11 of 192 fish caught). Twleve (19%) of the tagged steelhead (four radio-tagged and eight floy-tagged fish) were recaptured by angling. Of 28 radio-tagged steelhead, 23 (82%) were tracked through spawning and 20 (71%) were followed through emigration. Telemetric monitoring showed that tagged steelhead moved quickly through the lower river (0-25 km) and occupied stream reaches presently closed to all angling. Radio-tagged steelhead (n=4) migrated through a canyon locat
